AP Physics 1 Scoring Guide HW 1.3

These flashcards cover key concepts related to projectile motion and gravitational effects in physics.

Acceleration due to gravity

The rate of change of velocity of an object due to gravitational force, usually denoted as 'g'.

Projectile motion

The motion of an object thrown or projected into the air, influenced only by gravity.

Initial velocity

The velocity of an object at the moment it is released or starts moving.

Free fall

The motion of an object under the influence of gravity only, with no air resistance.

Maximum height

The highest point reached by an object in projectile motion.

Vertical velocity component

The portion of an object's velocity in the vertical direction.

Horizontal displacement

The horizontal distance traveled by an object in motion.

Gravitational field

A model used to explain the gravitational force exerted by a mass on surrounding masses.

Air resistance

The frictional force air exerts against a moving object, often considered negligible in physics problems.

Kinetic energy

The energy an object possesses due to its motion, calculated as 1/2 mv².

Potential energy

The stored energy of an object based on its position or height.

Inertia

The tendency of an object to resist changes in its state of motion.

Momentum

The quantity of motion an object has, dependent on its mass and velocity.

Constant acceleration

A situation where an object's acceleration does not change in time.

Time of flight

The total time a projectile remains in the air before it hits the ground.
